STAVETRIMMING OR JOINTING' MACHINE.

SPECIFICATION forming part of Letters Patent No. 484,460, dated October 18, 1892. Application filed August 6,1891. I Serial No. 4 1 (N m -l To all whom it may concern: springing the cutting-rest,and Fig.9 isaplan Be it known that I, CHARLES WILLIS RICH, view of a barrel-stave produced by my ima citizen of the United States, residing at proved machine. Summertowmin the county of Lawrence and In order to enable those skilled in the art 5 State of Tennessee, have invented new and to make and use my invention I will now deuseful Improvements in Stave Trimming or scribe the same in detail, referring to the Jointing Machines, of which the following is drawings wherein a specification. The numerals 1 indicate the end frames or The object of my invention is to provide standards of the machine,which are provided to novel means for simultaneously trimming or with suitable feet 2 for rigidly securing them jointing and recessing or notching the edges in position. The upper ends of the frames or of staves for the purpose of more rapidly prostandards are connected by a horizontal knifeducingthe staves and materially economizing carrying bar 3, preferably composed of an the manufacture of ventilating barrels or vesangle-iron, for the purpose of providing the 15 sels employed for transporting early apples, laterally-projecting flange 4, to which are adnew potatoes, and other fruits or vegetables. justably connected the angular plates 5,which The invention also has for-its object to procarry the stave trimming or jointing cutter vide a new and improved stave trimming or or knife 6. The plates 5, as shown, are com jointing machine whereby the curvatureat the posed of angle-irons and the rear surfaces of 20 edges of the staves can be varied toincrease the vertical flanges 7 of these angle-irons are or diminish the bilge of the barrel or vessel, beveled orinclined to provide the proper seat and to so form or shape the edges that when for the metallic knife or cutter 6, which is they are assembled they will fit closely tocomposed, preferably, of a continuous piece gether and produce a nice, smooth, and neat of properly-tempered spring-steel suitable for 25 barrel. the conditions required. The extremities of To accomplish all these objects, my inventhe horizontal knife-carrying bar 3 are contion involves the features of construction and nected with theend frames or standards by the combination or arrangement of devices suitable adjusting-bolts 8 in such manner hereinafter described and claimed, reference that either or both ends of the bar can be 0 being made to the accompanying drawings, raised or lowered as occasion may demand.

in which The horizontal flanges of the angular plates Figure 1 is a perspective View of a stave 5 are secured to the horizontal flange 4 of the trimming orjointing machine constructed in cutter-carrying bar 3 through the medium of. accordance with my invention. Fig. 2 is a clamping-bolts 9, which extend through slots 35 Vertical sectional view of the same. Fig. 3 is 10 in the flange 4 and through slots 12 in the a horizontal sectional view taken on the line plates 5, said slots 10 and 12 being arranged on m, Fig. 2, looking downward. Fig. 4 is a at right angles to each other, so that the plates similar view taken on the line y y, Fig. 2, 5can be adjusted lengthwise and transversely looking upward. Fig. 5 is a side elevation of with relation to the cutter-carrying bar. The 40 the stave trimming and recessing cutter or flange 4 is provided at each extremity with a knife. Fig.6 is a similar view of the cuttingpendent lug or projecting part 13, having a rest for supporting the stave while being set-screw 14., to bear against one extremity o trimmed and recessed. Fig.7 is a detail perof each adj usting-plate 5, and centrally bespective viewof the adjustable plates for suptween its extremities the flange 4 is provided 45 porting and springing the stave-trimming with a pendent bracket 15, provided with a knife into a greater or less longitudinalcurvpair of set-bolts 16, which respectively bear ature. Fig. 8 is a similar view of the adagainst the inner adjacent ends of the adjustable plates for similarly supporting and justing-plates 5. The stave trimming or jointing knife 6 is provided with a seriesof vertical slots 17, through which pass clampingscrews 18 for attaching the cutter or knife to the adj usting-plates 5, While rendering the cutter or knife susceptible of vertical adjustment relatively to said adj listing-plates; The object of this construction and arrangement is to enable the cutter or knife to be sprung longitudinally into a curve of greater or less radius for regulating the bilge of the barrel to be produced.

It will be obvious that if the set-screws 16 be adjusted to move the. adjoining extremities of the plates 5 in a direction toward the operator the leverage exerted by the said plates will spring the cutter or knife longitudinally, and by adjusting theset-screws to a greater or less extent: the cutter or knife is sprung longitudinally intoa curve of greaterorless radius. The set-screws 14, which act against the'onter' ends of the plates 5,-assist inadjusting the sections for springing the cutter or knife into a longitndinallycurved condition. v

The-endlframes or standards 1 of the machine-franne are provided with horizontallyprojecting'bars 19, to the outer-extremities of which are pivoted, as at 20, thetable-supporting arrns2l, carrying attheir rear end pertions the table 22, which, ashere shown, isangnlai imcrosssection for the purposeof: increasing its strength, while'making-irlight in weight. To the upper side of the table 22 are applied a pair'of adj usting=plates 23,composed ofangle-irons having the horizontal flanges connected with the table by clamping-bolts 24, which pass through suitable slots 25 in the side of each end with a set-screw 26, adapted to-bear against the outer extremity of one of the adjusting-plates 23, and centrally between its extremities the table is providedwith an upwardly-proj ecting bracket 27, havinga pair of set screws28,bearing, respectively, against the inner' adjacent extremities of the adj estplates 23 can be adjusted exactly the same as the adjusting-plates 5 for the purpose of springingan elastic cutting-rest 29 longitudinallyintoa curve of greater or less radius, aecording to thelongitudinal curve to which the trimming or'jointing knife 6 has been sprung; The cutting-rest 29 is composed of a :plate of spring-stock to render it susceptible of being spru nglongitudinally, and it is attached to the vertical flanges 30 of the adj ustingr-plates 23 through the medium of screwsorother' fastening devices. The lower portions-or hases of the-adjusting-plates 23 are provided with ledges or shoulders-31 to serve asabutments for the cutting-rest 29, thereby enabling the latter to resist the strains incident to the trimming or jointing operation.

- The adjusting-plates 23 carryapair'of restbars 32, which serve to support the staves as they are adjusted upon the cutting-rest 29, as will more fully hereinafter appear.

In the construction described and shown the series of plates 5 extend longitudinally along the elastic knife 6 and constitute a substantially continuous support along the length thereof, whereby. the knife cannot twist and is rendered strong and durable and susceptible of practicably eifecting the work to be performed. The plates 23 also extend longitudinally along the elastic cutting-rest 29 and constitute a substantially-continuous support for the same, while permitting such rest to be sprung into curves of difierent radii.

The table 22 is adapted to oscillate in the arc of a circle and-isconnected to the upper extremities'of rods or links 33, having their lower extremities adjustably connected withthe slotted portions 34: of arms 35, projecting rearwardly from a rocking treadle-bar- 36, having its extremities pivoted to the end framesor standards, as at 3-7. The rocking treadle-bar is provided with a foot treadle or lever 38, which can be depressed for the purpose of raising thetable 221 to efiect the trimming or jointing of the 'staves by the co-operating actionof the trimming cutter or knife 6 and the cutting-rest 29.

The connecting rodsor links33 areprovided with arock-shaft 39, on which are mountedthe lower extremities of a-pair of feed-armsAO, having theinupper extremities provided with suitably-shaped heads 41,;ar-

- ranged in such relation to the r stave-rests 32 i that when the feed-arms are swung in the proper direction a stave supported by the plates 23. The table is provided at the rear staverests 32 will be fed'or advanced into proper position upon the cutting-rest 29, so

that'when the table is elevated thetrimm ing or jointing knife will'accurately trim the edge of the stave and produce a longitudinal curvature on such edge corresponding to the longitudin-al curvature imparted to the trimming i cotton or knife and cutting-rest. ing plates 23, all in suchmanner'thatthe said i The feed-amused can be adjusted on the rock-shaft 39 by means of set-screws 4:2 for l the purpose of adjusting the heads 410i the f feed-armsinto correct operating position, as

occasion may require. Bymounting thefeed- I arms 40 upon therock-shaft39, carried bythe connecting rode on links 33 of the treadle 3 mechanism, the two feed-"armsare simultaneousiy moved byswinging one of them through the medium of a handle43, and such feedarms rise and fallv with the connecting rods or'links as they: move vertically to oscillate the table 22.

The slotted portions 34 of the arms 35 on the rocking treadle-bar 36 enable the stroke 1 of the table to be varied by adjusting the stroke of the table will be diminished, While by adjusting the lower extremities of the connecting rods or links away from the rocking treadle-bar the stroke of the table will be increased.

The shape of the cutting-edge of the cutter or knife 6 is clearlyshown in Fig. 5, and it is such that the central portion of the cutter or knife commences the cutting operation, and consequently a shear cut is produced from the center toward each end For the purpose of producing ventilating recesses or notches in the edges of the stave simultaneously with the trimming or jointing act-ion of the cutter or knife I provide the latter with aseries of laterally projecting cutting portions 44, which interrupt the continuity of the trimming or jointing cutting-edge and fulfill the conditions required to form recesses or notches in the edges of the staves simultaneously with the trimming or jointing thereof. The cutting-rest 29. is also provided with similarly-shaped cavities-or recesses 45, adapted to receive the laterally-projecting cutting portions 44 0f the cutter or knife 6.

The shape or configurationof the laterallyprojecting cutting portions 44 and of the cavities or recesses 45 may be largely varied without altering the character of my invention,it only being essential to so construct these parts that when the cutter or knife'acts to trim or joint the edge of the stave it will simultaneously therewith produce recesses or notches 46 in the edge of the stave 47, as clearly shown by Fig. 9,in such manner thatwhen the staves are assembled and 'secured'the recesses or notches in the edges of one stave register or match with the recesses or notches in the contiguous staves, and a barrelhaving ventilating-orifices is produced.

The number of laterally-projecting cutting edges 44 and cavities 45 can -be varied, ac cording to the number of recesses or notches it is desired to produce in the edges of the staves. I

I have indicated the laterallyprojecting cutting portions 44 as angular or approximately-V-shaped and the cavities or recesses 45 correspondingly formed, as this is a desirable construction for the purpose of producing the ventilating-orifices.

The recesses or cavities 45 are provided in the cutting-rest by shaping the latter with laterally-projecting portions exactly the same as the laterally-proj ecting portions of the cutter or knife 6; but I do not confine myself to this specific manner of producing the recesses or cavities 45 in the cutting-rest.

7 To produce perfect work, itis essential that the cutting-rest 29 moveclose to thecutter or knife 6, and this is rendered possible by the adjusting devices described and shown for enabling the several parts to be properly adj usted in'accordancewiththe conditions required.

The cutter or knife 6 is adapted to be slightly adjusted lengthwise through the medium of set-bolts 48, engagingthe brackets 13,v

secured to the flange 4 of the knife-carrying bar 3. The object of this is to adjust the knife slightly in a longitudinal direction to accurately register its laterally projecting cutting portions 44 with the cavities or recesses 45 of the cutting-rest 29. c

It will be observed that the beveled or .inclined sides of the flanges 7 on the adj ustingplates 5 are at the rear of the machine and the beveled edge 50 of the. cutter or knife 6 is presented toward the front side of the machine. By this arrangement I obtain better results, because the flanges 7 of the adjust: ing-plates 5 can project down in proximity to the edge of. the. cutter. or knife and close to the top portion of the beveled edge 50, there-: by affording greater support to the thin outter. or knife and rendering it less liable ,to spring uponthe cutting-rest 29 as the latter moves past such cutting-edge. The action of the wood while being cut tends to pull the cutter or knife forward, and this would spring the cutter or knife upon the cutting-rest 29, were such cutter or knife not braced and supported by the flanges 7 of the adj usting-sections 5,as hereinbefore. explained.

The cutter or knife 6 and the cutting-rest 29 can be conveniently detached for thepurpose of substituting a straight-edged cutter and a straight-edgedcutting-rest,if it be desired to use the machine without producing ventilating recesses or notches in the edges of the trimmed staves.

By providing a table and a cutting-rest which move in the arcof a circle and constructing the stave trimming or jointing cutter or knife with reverse inclined cuttingedges, I am enabled to so cut the staves that they have each edge continuouslyincreasing in angle of inclination from the center toward each end, as indicated at.5l, Fig. 9. This angle-is that producedby the edge of the stave relatively to the face or side thereof, such edge being beveled instead of. at right angles. to the face or side of the stave, as heretofore, and this bevel increases in angle of inclination from the center to the. end of the stave. The continuously-increasingangles 51 referred to result from the fact that the cutting-rest 29 moves in the arc of a circle and the cutter or knife 6 commences the cutting action at the center of the length of the stave. By this means thestavesfit. more closely together when assembled and secured and nicer, smoother, and neater joints are provided.
